Donald Trump and his allies have a new argument against Hillary Clinton amid FBI's renewed probe into her emails

Donald Trump and his allies have started to float a new line of
attack against Hillary Clinton after the FBI's announcment Friday
that it had discovered emails "pertinent" to its investigation of
her private email server.

"I'm now convinced that we will be facing the very real
possibility of a constitutional crisis with many dimensions and
deleterious consequences should Secretary Clinton win the
election," Trump said at a Michigan rally on Monday, quoting an
op-ed article from Doug Schoen, a pollster
for former President Bill Clinton who renounced his support of
Hillary Clinton, the Democratic presidential nominee, after the
latest FBI revelation.

"She would be under protracted criminal investigation and
probably a criminal trial, I would say," Trump said. "So
we'd have a criminal trial of a sitting president."

The Republican nominee added that he believed that investigation
would "last for years."

"Nothing will get done," Trump said. "I can tell you, your jobs
will continue to leave Michigan. Nothing's going to get done."

Top Trump backers echoed these claims, even as the FBI director,
James Comey, wrote in his bombshell Friday letter he "cannot yet
assess whether or not this material may be significant."

Fox News host Sean Hannity, a devout Trump supporter, and former
Rep. Jack Kingston of Georgia, a senior Trump adviser, said the
election of Clinton could lead to a "constitutional crisis."

Former House Speaker Newt Gingrich went as far as to tell Hannity
on his Monday television program that the new Clinton "campaign
slogan" should be "vote Hillary and get Tim Kaine for president."

Comey's letter to congressional leaders on Friday
came just 11 days before the November 8 election. The FBI
director has faced a barrage of attacks from prominent Democrats
and political analysts for commenting on the agency's
investigation.

"And first of all, for those of you who are concerned about my
using personal email, I understand, and as I said, I am not
making excuses," she said. "I have said it was a mistake and I
regret it, and now they apparently want to look at emails of one
of my staffers, and by all means they should look at them, and I
am sure they will reach the same conclusion when they looked at
my emails for the last year — there is no case here."
